Application filed` March 10, 1 908. Serial No. 420,239. I

'To all who-m it may concerns,

Be it known that I, FRANK E. CLoTz, a citizen of the United States, residing at Menominee, in the county of Menominee and State of Michigan, have invented a new and useful Projectile, of which the following is a specification. i l

This invention relates to projectiles for firearms and cannons, and has for its object to provide a projectile or bullet by means of which after it is discharged it will travel with less resistance, greater speed and a longer distance. 1 -Y The invention has for its object to provide a projectile or bullet of this description, as hereinafter set forth and claimed.

ln carrying out the invention, the projectile is formed with an axial or longitudinal passage from end to end of the same, and with a plug oi'pin at the rear endof the projeetile which closes said passage,

In the accompanying drawings ,Figure 1 represen-ts in longitudinal section a projectile constructed 1n accordance with this inven.

' tion.. Fig..2 is a similar. view with the retaining pin removed. Fig. 3 is a side view of a projectile with the retaining pin projecting from theforward end thereof.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figuresof the drawings.

1 indicates a pro'ectile provided with an ai'cial or longitudinal passage 2. At the rea-r end ofthe -projectile is formed afrecess or socket 3, opening into the passage 2, for the reception-of a plug 4, which sets into said r'ecess 3, with an approximately loose fit. When the projectile has left the gun, the air rushing through the passage 2 drives' the plug 4 but of the recess 3 and leaves the longitudinal passage through the projectile 1 open for the passage of air. In order to retain the plug 4 iii place during the loading of the gun,

i a pin 'o is provided, one endvof which seats into a socket or-hollow 6 in the front face-of the plug 4. After the projectile is placed.

against the powder, or in position for firing, the pin 5 -is -withdrawn. AIn order that the `plug 4 mayreadily be pushed or blown out of the' recess 3,4 it is referably formedwith tapering 'sides 7. y' means of this construction of the projectile thev air passing through the passage way 2 will-lessen the resistance to the projctileor bullet 'anolwill cause itjto move faster and in a 'direct line,

What is claimed is 1. A projectile-having a'longitudinal coi'i- I centric passage of uniform borethronghout,

and being provided at its rear en'd with van annular recess' having a conicaly side wall, the rear end of said recess being of greaterarea than the forward end thereof, and a' conical plug adapted to fit in the said recess,laiid having its forward side bearing againstjthe bottom of the recess, and-itsrear s ide flush.`

with the rear end ofthe projectile.

2. A projectile having a longitudinal -concentricpassage, of uniform bore throughout, and being provided inrits rear end with an annular recess, having a conical side wall, the

rear-end of the recess having greater area than the forward end thereof, aplug fitting snugly'within the recess and having its-forward side bearing against the bottone thereof, and its rear side occupying the same plane as that occupied by the rear end of the projectile, saidplug having in its forward side a 'in the. presence of two` witnesses.
